In vitro

Aurora A Inhibitor I is a 2,4-dianilinopyrimidine that selectively and potently inhibits Aurora A. Aurora A Inhibitor I effectively inhibits the proliferation of HCT116 and HT29 cells, with IC50 of 190 nM and 2.9 μM, respectively. The Aurora A selectivity of Aurora A Inhibitor I against Aurora B depends on a single amino acid (Thr217) of Aurora A. [1] In KCL-22 cells, Aurora A Inhibitor I (1-5 μM) increases G2/M cell fraction, induces histone H3 serine 10 phosphorylation, and suppresses mitotic Aurora A autophosphorylation on Thr288. Aurora A Inhibitor I (0.5-5 μM) also suppresses cell proliferation in KCL-22 cells, as well as BCR-ABL-negative leukemia cell lines KG-1 and HL-60. Aurora A Inhibitor I effectively induces apoptosis in KCL-22 cells at 5 μM. [2] In a recent study, Aurora A Inhibitor I is also found to inhibit cell growth of HCT116, HT29, and HeLa cells, with IC50 of 377.6 nM, 5.6 μM, and 416 nM. [3]

Protocol (from reference)

Kinase Assay:

[1]

  • Auroras A and B Inhibition Assays:

    Both Auroras A and B are assayed in ELISA format using a GST fusion (pGEX-4T) of the N-terminus of Histone H3 (aa 1−18) as substrate. Plates are coated with 2 μg/mL substrate in PBS then blocked with 1 mg/mL I-block in PBS. Kinase reactions are run for 40 min with 5 ng/mL (0.16 nM) Aurora A or 45 ng/mL (1.1 nM) Aurora B at 30 μM ATP (~ Km) in kinase buffer. Final DMSO concentration is 4%. Product is detected by incubation with antiphosphohistone H3 (Ser10) 6G3 mouse monoclonal antibody and sheep-anti-mouse HRP conjugate, followed by washing and addition of TMB substrate. After quenching with 1 M phosphoric acid, plates are read at 450 nM.

Cell Research:

[1]

  • Cell lines: HCT116 and HT29 cells
  • Concentrations: 0.1 nM - 10 μM, dissolved in medium lacking serum and glutamine (dissolved in DMSO as stock solution)
  • Incubation Time: 72 hours
  • Method:

    Cells are seeded in 384-well plates on day 0 in 50 μL of complete medium and incubated overnight in a 5% CO2 atmosphere at 37 °C. On day 1, 10 μL of Aurora A Inhibitor I is added. On day 4, plates are allowed to reach room temperature, and 30 μL Cell Titer-Glo reagent is added to each well to measure total ATP levels. Plates are read after shaking 15 min at room temperature.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
